Not really. Stuff happens in pvp. Getting supered is one. I rarely even is it to revive in crucible. Only if I get a 15 kill streak and someone supers me or I get group attacked. Get up and slaughter them all. But where as titan smash kills everything mine doesn't, so using it before I die isn't always an option. I could use it and immediately get nova or smashed because I used it. It's all about playing it smart.
